Combine multiple streams into one, shift selected streams to LSB side.

The first selected stream will be copied to LSB. The data within the stream will not change the bit-order.

_WIn input stream width.
_NStrm number of input streams.
select_cfg one-hot encoded selection, LSB for istrms[0].
istrms input data streams.
e_istrm end flag for all input streams.
